Comment 17 for bug 282287

Same problem here on Kubuntu Intrepid, latest updates applied.
Tried all sorts of solutions, even going for bleeding edge Nvidia 180.16 drivers, nothing stops Firefox from crashing. (although I now enjoy all the fancy 3D goodies on KDE 4.1.2)

Uninstalled winbind, samba and anything related to both, /etc/resolv.conf couldn't be simpler:
----------------------snip--------------------------------------------------------
# Generated by NetworkManager
nameserver 192.168.1.1
----------------------snap--------------------------------------------------------

/etc/nsswitch.conf:

----------------------snip--------------------------------------------------------
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

I don't think it's even related to Flash (running Flash 10) since it also happens on web pages devoid of Flash embedded joy. I bet it crashes on HTML 1.0 content just the same.
Symptoms that signal a problem in FF 3.0.5: corrupt right hand scroll bar.

Let me know if you guys need any other information.
